• In order to directly run Node.js® script code from a JS7 shell job script, the recommended approach is to use a shebang that runs Node.js® as the interpreter of the script like this:

  @@setlocal enabledelayedexpansion & @@findstr/v \"^@@[fs].*&\" \"%~f0\" | node.exe -NonInteractive -Command - & exit !errorlevel!/b& var  var name = (process.env.name); var num = parseInt(process.env.num); console.log(name); console.log(num);

  
  Explanation:

  • • If you consider this shebang replacement somewhat cryptic then add it to JS7 - Script Includes which are easily referenced from shell jobs, e.g. by using 
      //!include <name-of-script-include>
    • The node.exe executable as available from the Node.js® installation is executed by the shebang.
      
      

• In addition, a Node.js® script can be executed from a file located with the JS7 Agent that implements the job:
